              SPECTACULAR RESULTS FROM E12 Alluvials BULK SAMPLE

- Kimberley Diamond Company's (ASX: KIM, AIM: KDC) (Kimberley) 40%-owned
  subsidiary, Blina Diamonds NL (ASX: BDI) (Blina) has achieved highly
  encouraging results from bulk sampling of alluvial gravels to the south of the
  Ellendale 12 lamproite pipe.

- One bulk sample, BLBS216, returned a spectacular grade of 15.85 cpht[1] at
  an average stone size of 1.08 carats. The largest diamond recovered from the
  sample weighed 6.03 carats.

- Blina's alluvial results provide compelling evidence that a source of large,
  high-quality diamonds may occur as a phase within the Ellendale 7 pipe.

Blina has recommenced exploration on the E12 Alluvials, a project within the
Terrace 5 palaeo-channel system. The project area is located immediately to
the south of the Ellendale 12 lamproite pipe. Previous work suggested that the
diamondiferous gravels in this area are of higher grade and contain larger
diamonds than the typical Terrace 5 system. Blina is proposing to conduct a
trial mining program in the area.

Processing of bulk samples from various locations within the E12 Alluvial area
has recently been completed. The highlight was sample BLBS216, an 82 tonne
bulk sample, which delivered an exceptional grade of 15.85cpht with an
astonishing average diamond size of 1.08 carats. The large average diamond
size was due, in part to a 6.05 carat stone within the sample. Even excluding
this stone, the average diamond size would have been a very encouraging 0.64
carats. This is by far the best grade and average diamond size ever recorded
for a bulk sample in the Terrace 5 system. The table below provides highlights
of bulk sampling in the Ellendale 12 Alluvial area.

Diamonds in the 1.2 to 14mm range recovered


The source (or sources) of the E12 Alluvial diamonds has not been established.
Bulk sampling of the Ellendale 12 lamproite returned low concentrations of
small diamonds and it is considered highly unlikely that the alluvial stones
are derived from this pipe. A proportion of the diamonds have crystal forms
characteristic of stones sourced from the Ellendale 7 lamproite. In addition,
the diamondiferous gravels also contain clasts, reminiscent of the rim-rocks
from this pipe. This pipe is located several kilometres east and potentially
upstream of the E12 Alluvials, and Blina considers it a possible source for
the diamonds.

During 2006, Kimberley commenced a surface bulk sampling and a Bauer, wide
diameter drilling program over the Ellendale 7 lamproite. While this work
identified concentrations of large diamonds in near surface samples from some
areas of this pipe, these were not of the grade or stone size recorded by
Blina. Processing of samples from the Bauer drilling has not yet been
completed but Blina's alluvial results provide compelling evidence that a
source of large, high-quality diamonds may occur as a phase within the
Ellendale 7 pipe.
